Glasses will come in a variety of styles and prices from $20 to $70.
Cinemark and UltraStar theaters in San Diego and Huntington Beach California are some of the first in the country to offer up vending machines which carry premium 3D glasses. The glasses in question are supplied by Marchon 3D and are designed to offer style in addition to a better picture.
"Unveiling these EX3D vending machines will reach consumers as they walk in," says Marchon 3D president David Johnson. He says that the glasses offered in the machines will "provide the best viewing experience from a technological standpoint as well as guaranteed comfort and style that speaks to each person’s personality."
As far as the 3D effect goes, it's really hard to judge what's legitimate and what's fluff. In terms of comfort though, he makes a good point. If you're seeing a lot of 3D movies and it's just $20 to grab your own pair of more comfortable glasses many movie goers may see the value.
